<h1>Batch personalize</h1>
<p>
<em>If you have any questions, please mail <a
href="mailto:Su@TenThousandSu.com?subject=Personalize+underlay+batch">Su@TenThousandSu.com</a>. The price to personalize is 0.001 Ether per Square.</em>
</p>
<p>
Use this page to personalize Su Squares you own on TenThousandSu.com. If your Square was previously personalized using the old, more expensive method you will need to <a href="https://tools.tenthousandsu.com/unpersonalize.html">unpersonalize</a> it first.
</p>
<h2>Select top-left Square</h2>
<p>Which Square will be the topmost and leftmost Square you will personalize?</p>
<p>
<input id="top-left-square-number" type=number min=1 max=10000 required style="width:7em">
</p>
<h2>Enter title</h2>
<p>Enter a title for your Squares. Later you can change the title of each Square individually.</p>
<p>
<input id="title" type="text" maxlength="64">
</p>
<p><span id="title-count">0</span> of 64 bytes</p>
<h2>Enter URL</h2>
<p>Enter a URL for your Squares. Later you can change the URL of each Square individually. Typically this will start with <code>https://</code>.</p>
<p>
<input id="url" type="text" maxlength="96">
</p>
<p><span id="url-count">0</span> of 96 bytes</p>
<h2>Upload image</h2>
<p>Design your image carefully.</p>
<p>Do not use animation or transparency. PNG and some other formats can be used here.</p>
<p>Each Square is 10×10 pixels. For example, if the area you want to personalize is 3 Squares wide and 2 Squares tall, your image must be 30×20 pixels.</p>
<p>
<input id="image" type="file" accept="image/png, image/jpeg, image/gif">
</p>
<p>
Image status: <span id="image-status">no image selected</span>
</p>
<p>
<canvas id="image-preview" width="0" height="0"></canvas>
</p>
<h2>Preflight</h2>
<p>Click this button to prepare your batch personalization, no transaction or payment is made in this step. This
will overwrite anything already in the box.</p>
<p>
<button id="preflight" class="btn">Preflight</button>
</p>
<textarea id="preflight-output" style="width:100%;height:10em"></textarea>
<p>
To manually edit individual Squares, copy/paste to a spreadsheet, edit, and then copy/paste back here. If you
would like to personalize a non-rectangular area, delete any rows that are not needed.
</p>
<p>
Preflight status: <span id="preflight-status">preflight was not yet performed</span>
</p>
<h2>Personalize</h2>
<p>Click this button to personalize your Squares.</p>
